On a 2002 Mitsubishi Diamante, bank 2 sensor 1, which is the upstream oxygen sensor, is located on the exhaust manifold on the passenger side of the engine. It is positioned before the catalytic converter and is responsible for monitoring the air-fuel mixture for that bank of cylinders. Accessing it may require some maneuvering due to the engine layout, but it is typically reachable from the top of the engine.
The bank 2, Oxygen sensor 2, on a 1999 Mitsubishi Diamante is located on the passenger side of the vehicle. It is in the exhaust in the undercarriage.
On a 2002 Mitsubishi Diamante, the bank 1 sensor 2 oxygen sensor is located on the exhaust system, downstream of the catalytic converter. Specifically, you can find it on the exhaust pipe, closer to the rear of the vehicle. It is usually mounted in a threaded bung and may require some effort to access, depending on the vehicle's configuration.
Bank 1 is the side of the engine near the firewall. Bank 2 near the radiator. Sensor 1 is before the catalyse converter sensor 2 after the catalyse converter. In your case it is the O2 sensor that behind the firewall and after the CC.
Bank 1 Sensor 2 is located on the Right Hand Bank - After the catalytic converter. Meaning its on the bank closest to the firewall and after the catalytic converter. Call any Mitsubishi dealer and they will tell you where its @.
The Bank 2 O2 sensors on a 2002 Mitsubishi Diamante refer to the oxygen sensors located on the side of the engine that does not contain the #1 cylinder, typically the passenger side. Sensor 1 is the upstream O2 sensor that monitors the air-fuel mixture before it enters the catalytic converter, while Sensor 2 is the downstream sensor that checks the efficiency of the catalytic converter after the exhaust gases have passed through it. Issues with these sensors can trigger the check engine light and affect engine performance and emissions.
That is the pre - cat 02 oxygen sensor.
Bank one refers to side where ! 1 cylinder is and the sensor 2 is the rearmost(at the converter outlet).
Oxygen sensor: bank 1 sensor 2.
In a 2003 Mitsubishi Outlander, bank 1 sensor 2 is located on the exhaust system, specifically after the catalytic converter on the bank 1 side of the engine. This sensor monitors the level of oxygen in the exhaust gases to help manage emissions and fuel efficiency. To access it, you may need to lift the vehicle and work from underneath.
Mitsubishi Galant, 2002, 4-cyl, O2 sensor, bank 1 sensor 1 (upstream)... PART NUMBER: MR506364
On a 2004 Mitsubishi Galant, the O2 sensor bank 2 sensor 1 is located on the exhaust system. Specifically, it is positioned before the catalytic converter on the bank 2 side of the engine, which corresponds to the rear bank of cylinders. To access it, you may need to lift the vehicle for better visibility and reach. Always ensure the engine is cool before attempting to work on exhaust components.
Bank 1 is the bank of cylinders that contain the number 1 cylinder. O2 sensor 1 is the first O2 sensor in the exhaust system between the engine and the catalytic converter.
